Abstract:
The crystal structure of the title compound, [Cu(C(2)N(3))(C(2)H(3)N)(2)](n), features zigzag chains along the a axis that consist of alternating [Cu(MeCN)(2)] and dicyanamide units, the latter acting as bidentate ligands via both terminal N atoms. The Cu atom shows a slightly distorted tetra-hedral coordination sphere. The anionic and neutral ligands lie on different mirror planes (perpendicular to the b and a axis, respectively), while the Cu atom is situated on their inter-section. The asymmetric unit comprises one fourth of the formula unit.
